IMPROVEMENT IN METALLIC MATS.

Specification forming part of Letters Patent No. l30,08, dated August 27, 1872.

To all whom it may concern:

Be it known that I, FRANK G. JOHNSON, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and'useful Metallic Mat; and I do hereby declare that the following is a full, clear, and exact description of the construction of the same, reference being had to the annexed drawing making a part of this specification, in which- Figure 1 represents the mat as it appears when lying on the floor and viewed from above; Fig. 2, a corner section viewed from above, to show the manner of uniting the several parts of the mat; Fig. 3, a vertical section cut through the line a a, Fig. 2. i

v The nature and object of my invention consist in providing a mat made by bending thin narrow strips of metal fiatwise out of a straight line, and securely binding a series of these bent strips together in such a manner as to leave openings or spaces between them and bring the bearing and wear and tear u'pon'the mat, when in use, upon the edges of the strips of metal.

-To enable others skilled in the art to make and use my invention, I will describe it more I are placed side by side so as to bring their angles in juxtaposition, as shown at O 0, Fig. 2, thus leaving square open spaces, as G G, between the strips, for the passage of water,

surrounded by a straight strip, E E, of the same width, but not necessarily of the same thickness or material, and all bound and firmbolts, or rods F F.

I do not confine myself to the use of any particular kind of metal, as copper, zinc, iron, 850., may be employed; or iron may be used and the entire mat galvanized with zinc or other metal, which would more or less stiffen the mat by forming a metal union between the points of contact of the several strips; or several difterent metals may be employed in the same mat; Nor do I limit myself to bending the strips into right angles, as they may be bent into acute or obtuse angles, or they may be bent into a serpentine form, so long as they are bent out of a straight line, so as to form open spaces between them when combined to gether as above described.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the strips A A and B B, binding-rods F F, and surrounding borderstrip E E, arranged substantially in the manner and for the purpose set forth.
